Endometriotic Parietal Involvement of the Rectosigmoid
Conditions
Brief summary
Evaluate MRI criteria predictive of the type of surgery to be performed for an in sano resection of endometriotic involvement of the recto-sigmoid by a resection without opening of the rectal mucosa (shaving) versus a segmental resection.
Detailed description
PURPOSE: To retrospectively determine the accuracy of MRI rectal and pararectal signs in predicting a segmental resection of lesions located in the rectum until the recto-sigmoid junction. MATERIALS AND METHODS: Institutional review board approval for this study was obtained and waived written informed consent. The MR images of 61 patients treated for rectal endometriosis over a 6 years period were reviewed. Two blinded readers performed in consensus a systematic analysis of 7 rectal (length, transverse axis, thickness and circumference of the lesion, and presence of a convex base, submucosal edema and hyperintense cystic areas) and 4 pararectal (posterior vaginal fornix, parametrial, ureteral and sacro-recto-genital septum involvements) signs for each lesion. MR imaging results were compared with surgical procedure (shaving versus segmental resection). Efficacy parameters were calculated with 95 % confidence intervals (CIs).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Comparison of MRI data with intraoperative data and anatomopathology | Intraoperatively | MRI criteria of parietal involvement will be confronted with the type of surgery performed (shaving or segmental resection) A rectosigmoid parietal involvement will be defined by the nodular replacement of the normal signal of the digestive muscularis, on at least two planes of cuts or two different weightings. |
